I have both of those German BDs, and they look and sound great. The mono tracks are DTS-HD 1.0 I believe. FAFDM is pretty rough when compared to the remastered Fistful and GBU though - lots of dirt and scratches, and it has some artificial sharpening, but not enough to spoil it. Germany's is the only release which is 'uncut', including an additional shot of Clint being punched in the face.

The opening credits for Fistful are German. FAFDM is the US master, so it's fully in English, except for the opening card mentioning bounty killers. A little bit of editing would fix that.
